This method does not work automatically and it seems to only work manually. I have added these notes here until one day when it is fixed. I now have one entry per host without using groups.
With NoIP you can optionally group hosts together and update them as one:
For this example we will assume you are:
Note: Check the IPFire WebUI > Logs > System Log > Section: Dynamic DNS. And check it again 15 Min later to see if it still works.
NoIP supports a group password, so you don’t have to use your main password remotely.
User name becomes "myGroup:myAddr@domain.com", if you want to try it.
